Quick background: I run a premium online tutoring business for high school students. We hold a sales call with every lead, and send them an email and text summarising the conversation with the link to purchase their first package. We heavily customise the email to reflect their specific goals. The win: a Claude skill now goes to a google sheet with my call notes, finds the customer I just spoke to and customises the email template to their gender, position (student/parent), subject, and even their goals, and leaves the draft in my inbox with addressee, subject and body complete. It also displays the SMS text for me to copy and send in my text system. Relevance: I'm sure you can imagine if you are holding calls with sellers, this allows you to genuinely reflect your conversation in a personalised email and text without you having to reinvent the wheel every time. Just take the notes once during the call and get Claude to do your writing for you. Time saved: 10-15 minutes per email and text pair sent.
